Excitation functions for the yields of ten residual nuclides from the /sup 12/C+/sup 20/Ne reaction have been measured over the range E/sub c.m./ = 11--33 MeV in steps of 150 keV, using ..gamma..-ray techniques. The magnitude and energy dependence of the excitation functions for most partial yields, as well as for the total fusion yield, closely resemble those from the /sup 16/o+/sup 16/O system when compared at the same compound-nuclear excitation energy. The total fusion yield exhibits strong anomalies at E/sub c.m./ = 22.7 and 24.1 MeV, while the 'u2/sup 0/Ne inelastic scattering yield exhibits a strong uncorrelated structure at E/sub c.m./ = 21.1 MeV. In addition weaker structure is seen at E/sub c.m./ = 13.6, 16.6, 18.6, and 26.3 MeV in the total fusion yield. The 24.1 meV resonance corresponds to a characteristic structure in the /sup 16/O+/sup 16/O reaction yields. Both structures appear at the same /sup 3/'u2S excitation energy and are found to be correlated with the transition to regime of limited fusion.
